CALENDAR.

SPECIFICATION forming part of Letters Patent No. 266,289, dated October 24, 1882.

Application filed April 10, 1882. (No model.)

To all whom it may cancersU Be it known that I, ELROY N. HEATH, of Boston, in the county ot' Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Calendars, and I do hereby declare that the followingis a full, clear, and exact description of the invention, which will enable otherslskilled in the art to which it appertaius to make. and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which i'orin a part of this specification.

Figure l represents the sliding card 5 Fig. 2, the main card; Fig. 3, the two cards together, forming the complete calendar.

rThis invention relates to improvements in calendars, more especially those which last for only one year; and its object is to simplify the devices heretofore used, and to produce one in which the monthly changes are made with certainty and without danger of mistake.

v The invention consists in a calendar having the. construction hereinafter set forth and claimed.

ln the accompanying drawings, the letter A represents a card of anysuitable size and shape. ln this card there are made two vertical parallel slits, a a. -0n a horizontal line,just above the space between these slits, are printed in order the names of the days of the week. In a similar position below, but between the ends ofthe slits, are arranged the names ofthe months in the manner hereinafter explained. Below these may be placed the directions for using the calendar, and around the whole a tasteful border.

The sliding card B is provided with crossing lines b b', which divide its surface into spaces, as shown. In the series of spaces which are thus formed are placed the numbers of the days of the month, each number, except those occupying the middle column-viz., l, S, 15, 22, and 29-being once repeated, the duplicate coming in the seventh space from the original. In the space at the bottom ofthe card, below the middle column of figures, is cut a notch, U, which, when the cards are in place, exposes the months behind. The card B is slipped through the slits a u', and thereby held to the card A. The names ot' the months are arranged in sets in such predetermined order that when the card B is slid so as to bring the notch C at a given month the column of figures will be in proper position under the days of the week for the month. Arrows or indicators c are placed at the name of the months, showing` by their heads which way the card B is to be moved to bring the notch to the ensuing mouth, thereby causing the change to be made quickly.

Having described my inventiomwhat- I claim as new, and desire to secure by Letters Patent, 1s-

The main card A, having the slits a a made therein and the naines ofthe days ofthe week above the space between the slits and those of the months between the lower ends ofthe slits, in combination with the sliding card B, having the numbers of the days ofthe month arranged as described, and provided with a notch, C, at its bottom edge, whereby the latter card is held to the former simply by resting in the slits and the proper month is exposed at the notch, as set forth. v

In testimony thatIclaim the foregoing as my own I affix my signature in presence of two witnesses.

ELROY N. HEATH.
